Walter SST Corecut 5/8-Inch Annular Cutter for Stainless Steel

Cut Stainless Steel Faster and Cleaner

If you have ever tried to drill a 5/8-inch hole through stainless steel plate with a standard twist drill, you know the struggle: the bit wanders, the metal heats up and hardens, and you end up burning through expensive drill bits while fighting the drill. The Walter 05E010 SST Corecut Annular Cutter is the solution to that headache. Designed specifically for use with magnetic drills, this cutter slices through stainless steel and hard alloys with ease, leaving you with a perfect, burr-free hole in a fraction of the time.

The secret lies in the "Corecut" design. Instead of grinding the entire volume of the hole into chips, this tool cuts a clean ring and ejects a solid slug. This means your drill doesn't have to work as hard, and you don't have to push as hard. For welders and fabricators, this translates to less fatigue and faster job completion. The SST series is built tough to handle the heat generated by stainless steel, maintaining its cutting edge longer than standard high-speed steel cutters. It is the ideal choice for fabricating brackets, mounting plates, or structural beams where precision and speed are non-negotiable.

Compatibility is never an issue with the Walter 05E010. It features a Universal Shank that fits both standard Weldon shank drills (with the two set screws) and quick-change Nitto style chucks. Whether you are running a Hougen, Jancy, Fein, or Milwaukee mag drill, this cutter will lock in securely and get to work. The 1-inch depth of cut covers most standard plate thicknesses encountered in general fabrication and MRO work.

To get the most out of this tool, we recommend using a high-quality cutting lubricant or coolant. This helps flush chips and keeps the cutter cool, further extending its life. Stop fighting with dull twist drills and work-hardened material. Upgrade your mag drill setup with the Walter SST Corecut and experience the difference that premium, application-specific tooling makes on your next stainless steel project.
